Plain-English summary
A 13-year-old spayed female dog was found to have a mass in her left ear that was not clearly connected to the surrounding cartilage. After examination, the mass was diagnosed as a well-differentiated liposarcoma, which is a type of cancer made up of fat cells, along with some cartilage-like tissue. This case is notable because it's the first time this specific type of tumor has been reported in the ear of a dog. Treatment options would typically involve surgical removal of the mass, but the outcome details are not provided.

Abstract
A 13-year-old spayed female dog had a mass in the left auricle. Grossly, connection between the mass and original auricular cartilage was not recognized. The mass was unencapsulated and contained multiple islands of mature hyaline cartilage and neoplastic adipocytes. The neoplastic cells comprised predominant mature adipocytes, scattered lipoblasts and irregular round to spindle cells with moderate atypia. The atypical cells occasionally had lipid droplets. A diagnosis of well-differentiated liposarcoma (WDL) with chondroid metaplasia was made. This is the first report for liposarcoma with chondroid metaplasia in the auricle of domestic animals.
